【保姆级】Python项目部署到Linux生产环境（uwsgi+python+flask+nginx服务
1.安装python我这里是3.9.5版本
安装依靠：
yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make -y 根据本身的需要下载对应的python版本：
cd /usr/local
wget https://www.python.org/ftp/python/3.9.5/Python-3.9.5.tgz 解压 > 编译 > 安装
tar -xvf Python-3.9.5.tgz
cd /usr/local/Python-3.9.5
./configure
make all
make install
Python解释器配置清华源：
pip3.9 config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple/ 2.假造环境配置
1）安装 virtualenv
pip3.9 install virtualenv 2）创建假造环境（一样寻常是一个项目一个假造环境）
mkdir home/python_item/envs
cd /home/python_item/envs/
virtualenv /home/python_item/envs/tender --python=python3.9
3）激活假造环境
source/home/python_item/envs/tender/bin/activate 4）安装项目依靠
cd /home/python_item/tender_project #进入项目目录
pip3.9 install flask
pip3.9 install lxml
pip3.9 install pymysql
pip3.9 install requests 3、uwsgi安装
1）安装uwsgi
激活虚拟环境，在虚拟环境中安装
source/home/python_item/envs/tender/bin/activate
pip install uwsgi 2）基于uwsgi配置文件的方式运行flask项目
socket = 127.0.0.1:8001
chdir = /home/python_item/tender_project
wsgi-file = main.py
callable = app
processes = 1
virtualenv = /home/python_item/envs/tender/ 3）启动项目
uwsgi --ini tender_test.ini 报错：
(tender) # uwsgi --ini tender_test.ini
getting INI configuration from tender_test.ini

解决：
urllib3版本不兼容，卸载重装
pip3.9 uninstall urllib3
pip3.9 install urllib3==1.22 重启即可
uwsgi --ini tender_test.ini nginx
安装：Linux安装Nginx
配置：
upstream flask {
server 127.0.0.1:8001 weight=1;
}
server {
listen 80;
server_namelocalhost;
#charset koi8-r;
#access_loglogs/host.access.logmain;
location / {
root html;
indexindex.html index.htm;
}
location /tenderTest {
uwsgi_pass flask;
include/usr/local/nginx/conf/uwsgi_params;
# indexindex.html index.htm;
}
location /test/ {
uwsgi_pass 127.0.0.1:8002;
include/usr/local/nginx/conf/uwsgi_params;
# indexindex.html index.htm;
}
#error_page404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504/50x.html;
location = /50x.html {
root html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000

# include fastcgi_params;
#}
# deny access to .htaccess files, if Apache's document root

#

# denyall;
#}
} 4.访问成功

5.编写脚本快速重启/制止
reboot.sh
#! /usr/bin/env bash
echo -e "======================wsgi process======================"
ps -ef|grep tender_test.ini |grep -v grep
sleep 0.5
echo -e "======================going to close ======================"
ps -ef | grep tender_test.ini | grep -v grep | awk '{print $2}' | xargs kill -9
sleep 0.5
echo -e "======================check if the kill action is correct ======================"
/home/python_item/envs/tender/bin/uwsgi --ini tender_test.ini & >/dev/null
echo -e "======================started... ======================"
sleep 1
ps -ef | grep tender_test.ini |grep -v grep stop.sh
echo -e "======================wsgi process======================"
ps -ef|grep tender_test.ini |grep -v grep
sleep 0.5
echo -e "======================going to close ======================"
ps -ef|grep tender_test.ini | grep -v grep | awk '{print $2}' | xargs kill -9
sleep 0.5 在项目目录下实验重启或制止，脚本放在下面，根据本身的现实环境举行修改即可
更新权限
chmod 775 reboot.sh
chmod 775 stop.sh 启动！
./reboot.sh
./stop.sh
